Back by popular demand, Husky's roller provides all the basic roller functions to equip short bed trucks for towing 5th wheel trailers weighing up to 16,000 pounds. Husky's economical roller provides needed truck-to-trailer clearance for low speed maneuvers. Installs with just four pins and clips. The Husky Roller's lift adjustment lets you minimize the distance between the wheels and the rails for smooth operation. It even includes two handles for versatility: one for the Husky 16KS, and one for the 16KW. Works in the base rail slots spaced 20-5/8 inch apart (base rails not included). Husky recommends using the #32059 Center Bolt Kit for proper installation. Use only Husky 5th wheel hitches with the Husky 16K Roller. Husky center bolt (item #32059) recommended.
